sencha package native for iPhone 5 not full height

When I run,

sencha package run <myconfig>.json

It launches the app in the simulator nicely. However, when testing on Retina 4-inch (iPhone 5) it appears that the app is not going full height – rather it's only as high as a 3.5-inch display iPhone <= 4s.

Is this expected to work or is it still to come? If it's pending I'll just wait for it and not keep trying.
